The document discusses key concepts in object-oriented programming including objects, classes, messages, and requirements for object-oriented languages. An object is a bundle of related variables and methods that can model real-world things. A class defines common variables and methods for objects of a certain kind. Objects communicate by sending messages to each other specifying a method name and parameters. For a language to be object-oriented, it must support encapsulation, inheritance, and dynamic binding.
Basic concepts of object oriented programmingSachin Sharma
This document provides an overview of basic concepts in object-oriented programming including objects, classes, data abstraction, encapsulation, inheritance, polymorphism, binding, and message passing. Objects are run-time entities with state and behavior, while classes define the data and behavior for objects of a similar type. Encapsulation binds data and functions within a class, while inheritance allows new classes to acquire properties of existing classes. Polymorphism enables one function to perform different tasks. Binding determines how function calls are linked, and message passing allows objects to communicate by sending requests.
Object oriented programming is a modular approach to programming that treats data and functions that operate on that data as objects. The basic elements of OOP are objects, classes, and inheritance. Objects contain both data and functions that operate on that data. Classes are templates that define common properties and relationships between objects. Inheritance allows new classes to acquire properties of existing classes. OOP provides advantages like modularity, code reuse, and data abstraction.
This presentation deals with pure object oriented concepts and defines basic principles of OOP's like Encapsulation , polymorphism , Inheritance and Abstraction.
This document defines object-oriented programming and compares it to structured programming. It outlines the main principles of OOP including encapsulation, abstraction, inheritance, and polymorphism. Encapsulation binds code and data together for security and consistency. Abstraction hides implementation details and provides functionality. Inheritance allows classes to acquire properties from other classes in a hierarchy. Polymorphism enables different types to perform the same methods.
An overview of object oriented programming including the differences between OOP and the traditional structural approach, definitions of class and objects, and an easy coding example in C++. This presentation includes visual aids to make the concepts easier to understand.
This all is about the object oriented programming in c++ language. It includes the importent components of oops , related terminologies and the related details.

Inheritance allows new classes called derived classes to be created from existing classes called base classes. Derived classes inherit all features of the base class and can add new features. There are different types of inheritance including single, multilevel, multiple, hierarchical, and hybrid. A derived class can access public and protected members of the base class but not private members. Constructors and destructors of the base class are executed before and after those of the derived class respectively.
A class diagram shows the structure of a system through classes, attributes, operations, and relationships between classes. It includes classes and their properties like attributes and methods. It also shows relationships between classes like associations, aggregations, generalizations, and dependencies. The class diagram is a key tool in object-oriented analysis and design.
This document provides an overview of object-oriented programming (OOP) including:
- The history and key concepts of OOP like classes, objects, inheritance, polymorphism, and encapsulation.
- Popular OOP languages like C++, Java, and Python.
- Differences between procedural and OOP like top-down design and modularity.
Object-oriented programming (OOP) uses objects that contain data and methods. The four pillars of OOP are abstraction, encapsulation, inheritance, and polymorphism. Abstraction hides unnecessary details, encapsulation shields an object's internal representation, inheritance allows subclasses to inherit attributes of superclasses, and polymorphism enables processing objects differently depending on their type. Classes define objects and contain data fields and methods, with objects being instances of classes that allocate space in memory. Access control in Java includes private, public, default, and protected access types.
Here are some common applications of object-oriented programming and C++:
- Desktop applications like word processors, spreadsheets, etc. The document is an object and formatting, editing operations are methods.
- Game development. Characters, weapons, levels etc. are modeled as objects with behaviors and properties.
- GUI (Graphical User Interface) toolkits like MFC, Qt. Windows, buttons etc. are predefined object classes.
- Web applications and frameworks. Objects represent pages, forms, database entities etc.
- Database connectivity libraries. Objects used to represent rows, columns, connections etc.
- Operating system design. Processes, files, devices modeled as objects.
- Scientific and engineering

The document discusses the key concepts of object-oriented programming (OOP) in C++, including objects, classes, abstraction, encapsulation, inheritance, polymorphism, overloading, and exception handling. Objects are instances of classes that contain data members and member functions. Classes define the blueprint for objects and allow data and functions to be bundled together. Abstraction hides unnecessary details and focuses on essential information. Encapsulation binds data and functions together within a class. Inheritance allows code reuse through deriving a new class from an existing class. Polymorphism and overloading allow functions to operate on different data types. Exception handling manages errors at runtime.
Object oriented programming is an approach that partitions memory into areas for data and functions that can be used as templates to create copies of modules on demand. The document discusses basic object oriented programming concepts like classes, objects, inheritance, encapsulation, polymorphism and dynamic binding. It provides examples of classes like Dogs and Birds and how inheritance and polymorphism work. Popular object oriented programming languages are listed as C++, C#, Java, PHP, VB, and VB.net and applications are given as real-time systems, simulations, databases, AI systems and more.
The presentation provides an overview of object-oriented programming (OOP) concepts. It discusses how OOP involves writing programs based on objects, and defines a class as a group of objects that share attributes and behaviors. An object is an instance of a class that contains all the variables and functions of that class. Key characteristics of OOP discussed include inheritance, data abstraction, encapsulation, and polymorphism. Inheritance allows new classes to inherit properties from existing classes. Data abstraction hides background details and simplifies development. Encapsulation binds data to the functions that operate on it. Polymorphism enables different types of objects to respond to the same function name. Examples of OOP languages provided are C++, PHP, and
This document provides an overview of object-oriented programming concepts including classes, objects, inheritance, abstraction, encapsulation, and polymorphism. It defines OOP as an engineering approach for building software systems based on modeling real-world entities as classes and objects that exchange messages. Key concepts are explained such as classes defining attributes and behaviors of objects, objects being instances of classes, and communication between objects occurring through messages. The four main principles of OOP - inheritance, abstraction, encapsulation, and polymorphism - are also summarized.
The document discusses object-oriented programming (OOP). It defines some key concepts in OOP including objects, classes, abstraction/encapsulation, inheritance, and polymorphism. Objects have identity, state, and behavior. Classes group similar objects and define their attributes and methods. Abstraction hides unnecessary details, while encapsulation bundles related data and functions into a class. Inheritance allows classes to inherit characteristics from other classes. Polymorphism means an object can take on multiple forms. Benefits of OOP include reusability, extensibility, understandability, and protection.
The static keyword in Java is used for memory management and can be applied to variables, methods, blocks, and nested classes. Static variables and methods belong to the class rather than objects. A static variable is loaded when the class is loaded and there is only one copy per class, while instance variables are loaded each time an object is created. The main method must be static since it is called before any objects are created to start the program execution. Static blocks are used to initialize static variables and are executed when the class is loaded.
This presentation provides an overview of object-oriented programming (OOP). It discusses key OOP concepts including objects, classes, encapsulation, inheritance, polymorphism, and message passing. Objects are instances of classes that have both data and behaviors. Classes define common properties and methods for objects. Encapsulation binds together an object's data and methods, while inheritance establishes a hierarchy where derived classes inherit from base classes. Polymorphism allows the same message to be interpreted differently, and message passing facilitates communication between objects.
Object-oriented programming (OOP) involves splitting a program into objects that contain both data and functions. OOP allows developers to define objects, their properties, and relationships. Classes are blueprints that define objects and don't use memory, while objects are instances of classes that hold both data and methods. Key concepts of OOP include inheritance, abstraction, polymorphism, and encapsulation.
This document provides an overview of object-oriented programming concepts using C++. It discusses key OOP concepts like objects, classes, encapsulation, inheritance, polymorphism, and dynamic binding. It also covers C++ specific topics like functions, arrays, strings, modular programming, and classes and objects in C++. The document is intended to introduce the reader to the fundamentals of OOP using C++.
A class is a code template for creating objects. Objects have member variables and have behaviour associated with them. In python a class is created by the keyword class.
An object is created using the constructor of the class. This object will then be called the instance of the class.
Everything about OOPs (Object-oriented programming) in this slide we cover the all details about object-oriented programming using C++. we also discussed why C++ is called a subset of C.
This document provides an overview of object-oriented programming concepts including objects, classes, messages, encapsulation, inheritance, polymorphism, and dynamic binding.

The document also explains how objects communicate through messages and the requirements for a language to be object-oriented, including support for encapsulation, inheritance, and dynamic binding.
If you want to program just about anything these days,
you’d better learn object-oriented programming.
Anyone should write a framework and never use it !
Who cares, right? We have the framework! We don't need to know how to "do it by hand"! Right?

The document discusses object orientation and compares procedural and object-oriented programming. It defines key concepts in object-oriented programming like classes, objects, inheritance, encapsulation, and polymorphism. It also provides an example of a local class in ABAP with methods to retrieve and display data from database tables.
Object-oriented programming uses objects that contain both data and behavior. Classes define common attributes and behaviors of objects. Objects are instances of classes and interact by sending and receiving messages. Key concepts include encapsulation, inheritance, polymorphism, and abstraction. Classes can inherit attributes and behaviors from superclasses, and subclasses can override inherited methods. Object-oriented design focuses on identifying real-world objects and classes and organizing them in class hierarchies to maximize code reuse.
Overview of Object-Oriented Concepts Characteristics by vikas jagtapVikas Jagtap
Object-oriented data base systems are proposed as alternative to relational systems and are aimed at application domains where complex objects play a central role.
The approach is heavily influenced by object-oriented programming languages and can be understood as an attempt to add DBMS functionality to a programming language environment
This is a presentation I did for the Cedar Rapids .NET User Group (CRineta.org). It was intended to present object oriented concepts and their application in .NET and C#.
Object-oriented programming (OOP) is a paradigm that splits programs into objects that contain both data and functions. Classes define the attributes and behaviors of objects. Objects are instances of classes that encapsulate their state and behavior. Key concepts of OOP include inheritance, abstraction, polymorphism, and encapsulation.
This document provides an overview of object oriented analysis and design using the Unified Modeling Language (UML). It discusses key concepts in object oriented programming like classes, objects, encapsulation, inheritance and polymorphism.

Finally, it introduces UML and explains how use case diagrams can be used to model the user view of a system by defining actors and use cases.
The document discusses object oriented programming concepts in ABAP, including:
1. Classes define objects and contain components like attributes and methods. Objects are instances of classes.
2. Classes can be declared globally or locally. Global classes are stored centrally while local classes are defined within a program.
3. Key object oriented programming concepts like inheritance, abstraction, encapsulation and polymorphism are explained with examples in ABAP.
4. An example program is provided to demonstrate creating a class to manage a bank account balance, with methods to set the balance, deposit amounts, and withdraw amounts.
This document provides an overview of object-oriented programming concepts. It begins by defining a programming language and different levels of abstraction in languages. It then defines object-oriented programming as relying on classes and objects, with classes acting as blueprints for objects. The basic building blocks of OOP - objects, classes, attributes, and methods - are introduced. Each concept is then defined in more detail, including objects, classes, inheritance, encapsulation, abstraction, and polymorphism. The document concludes by outlining some advantages of using an object-oriented programming approach.

This document discusses key concepts of object-oriented programming including inheritance, polymorphism, and dynamic binding. It describes how inheritance allows for reuse of data and functionality from parent classes while also allowing modification and addition of new entities in derived classes. Polymorphism is supported through dynamic binding which allows polymorphic variables to reference objects from parent and subclass types.
Object-oriented programming organizes software around data objects rather than functions. The key concepts are encapsulation, inheritance, and polymorphism. Encapsulation treats an object's data and methods as a single unit, inheritance creates class hierarchies where subclasses inherit attributes and behaviors from parent classes, and polymorphism allows the same method to work differently for different classes. The main building blocks are classes, which act as templates for objects, and methods, which define objects' behaviors.
This document provides an overview of object-oriented programming concepts and Java programming. It discusses key OOP concepts like classes, objects, encapsulation, inheritance, and polymorphism. It then covers the history and development of Java, describing how it was initially created at Sun Microsystems in the 1990s to be a platform-independent language for programming consumer electronics. The document outlines some of Java's key features like being simple, secure, portable, robust, and architecture-neutral. It also discusses Java's object-oriented nature and support for multithreading.

This document discusses object-oriented concepts and modeling. It begins by listing three textbooks on these topics. It then provides an overview of object-oriented concepts like objects, classes, inheritance, polymorphism, and encapsulation. It describes the stages of object-oriented analysis, design and implementation. It discusses the three main models used in object-oriented modeling: class models, state models, and interaction models. Finally, it covers object-oriented themes like abstraction, encapsulation, and polymorphism and the purposes of modeling.
Software objects contain state and behavior. An object's state is stored in fields and its behavior is exposed through methods. Hiding internal data and only allowing access through methods is known as encapsulation. Common behavior can be defined in a superclass and inherited into subclasses using the extends keyword. A collection of related classes organized into a namespace is called a package.
This document provides an overview of common object-oriented programming (OOP) concepts and interview questions. It discusses key OOP concepts like classes, objects, encapsulation, inheritance, polymorphism, and abstraction.

A.I. refers to the capability of machines to imitate intelligent human behavior. The history of A.I. began in the 1950s but has improved greatly in recent decades with advances like Sophia robot. A.I. is needed because humans have physical limitations, while robots can perform dangerous jobs. A.I. is created through a combination of programming, hardware, and sensors. It has many applications like healthcare, education, industry, finance, and customer support. While A.I. provides benefits like low error rates and replacing humans in dangerous jobs, there are also disadvantages such as high costs, lack of creativity, and potential unemployment. The future of A.I. could include automated transportation, cyborg technology

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.

4. What is an Object?
An object is a software bundle of related variables and
methods. Software objects are often used to model real-
world objects you find in everyday life.
Visual representation of a software object A bicycle modeled as a software object
5. What is a Class?
A class is a blueprint or prototype that defines the variables
and the methods common to all objects of a certain kind.
Class is an implementation of an abstract data type and
so encapsulates both data and operations.
Object is run-time instance of class.
Classes just sit there, objects do the real work.
Memory is allocated for Objects not for Classes.
6. What is a Message?
Software objects interact and communicate with each
other using messages.
The object to which the message is addressed (YourBicycle)
The name of the method to perform (changeGears)
Any parameters needed by the method (lowerGear)

8. To be object oriented, a language must support
Encapsulation
Inheritance
Dynamic Binding
Some of the popular OO languages are
C++
Smalltalk
Java
Eiffel
FORTRAN90
CLOS(Common Lisp Object System)
Ada95
Modula-3
9. Encapsulation:
Packaging an object's variables within the protective
custody of its methods is called encapsulation.
Often, for practical reasons, an object may wish to expose
some of its variables or hide some of its methods.
Access Levels:
Specifier Class Subclass Package World
Private X
Protected X X X
Public X X X X
11. What is Inheritance?
A class inherits state and behavior from its superclass.
Inheritance provides a powerful and natural mechanism for
organizing and structuring software programs.
Super Class
Subclasses
12. Properties:
Each subclass inherits state (in the form of variable declarations) from the superclass.
Subclasses can add variables and methods to the ones they inherit from the superclass.
Subclasses can also override inherited methods and provide specialized
implementations for those methods.
You are not limited to just one layer of inheritance. The inheritance tree, or class
hierarchy, can be as deep as needed.
Benefits:
Re-Usability
Subclasses provide specialized behaviors from the basis of common elements provided
by the superclass. Through the use of inheritance, programmers can reuse the code in
the superclass many times.
Can define Abstract Classes
Programmers can implement superclasses called abstract classes that define "generic"
behaviors.
14. Dynamic Binding:
Dynamic binding occurs when the type of variable changes at run-
time.
A common way for a variable to change its type is via assignment.
Bike:= MoutainBike is safe
MountainBike:=Bike is not safe
MountainBike is declared to have all the features of Bike so the
assignment does no harm.
A variable that starts life of the type Bike may be attached to any
object that is a kind of Bike, including MountainBike,RacingBike,…
A variable that starts life of the type MountainBike can only be
attached to MountainBike objects but does not include RacingBike or
general Bike.
15. Polymorphism:
The ability to appear in many forms.
In object-oriented programming,
polymorphism refers to a programming
language's ability to process objects differently
depending on their data type or class.
It is the ability to redefine methods for
derived classes.
E.g. e-bike Acceleration system.
